....would be the best for a mix of gas mileage and hp, also want to know about a set of plug wires?

There is no such thing. Spark plugs and wires do not make performance and mpg. They either work or they don't. It's not a component that can be enhanced. Anything that says otherwise is fictitious advertising.

Our trucks came with 3 Nickel Plugs and 3 Platinum Plugs out of the factory. If you go to your dealership or call them and ask what plug for our trucks, they will say the Nickel ones. Not everyone likes running nickel ones. So get the SP-498s from Advance Auto online and put in a discount code and pick them up at local store. alot cheaper that way.
